Porkensioner Bracket evolution and versions
I am only kind of a bad guy and I am not trying to instigate another flame war.
Before I even ask a question, I wish to lay down two alternative worldviews and ask that all assign themselves one or the other temporarily. Having done that, perhaps we can all just respectfully agree to disagree over which is right.
1. The porkensioner and associated bracket is an engine killer because its a home garage hack dreamed up by someone who has just enough knowledge to be dangerous. Revisions in the design are proof that it was and is fundamentally unsound in both concept and execution. Those who use it are undisciplined, lazy and impure in heart and spirit. They do not respect the superior engineering of the factory part and likely have some Italian blood in their background. Moreover, laboratory mice fed an exclusive diet of porkensioner brackets showed an increased incidence of uterine cancer.
2. The porkensioner may be the most significant advance since the invention of the integrated circuit. It is vastly superior to the factory tensioner, which was designed by Porsche engineers to both maintain a semblance of belt tension and keep 928 owners returning to the dealership for service. Even if it uses an Audi tensioner intended for a different application and and has undergone some design revisions, those who criticize it are motivated by greed, malice and a belief that a 928 can only be maintained by a select society of black robed technicians who found servicing space shuttles between flights insufficiently challenging. Any failures of the porkensioner in service are due to anomalies and revisions in the product are no more significant than the multiple revisions seen in the 928 itself, many of which improved the reliability and performance of the vehicle while maintaining a fundamental component of its character - fixing even the simplest thing can be a pure bitch.
Having wasted my time in writing the above (and yours if you are still reading), I don't give a rat's a** which camp you may belong to or what oil you use. Here's are my questions:
The porkensioner appears to have three bracket versions, Yellow Zinc plated, Black and Silver. The first version had threaded holes for the fasteners securing the tensioner arm and roller to the bracket. The second (Black) discarded the threaded holes for unthreaded holes so the bolts retaining the lever arm and roller would pass through the bracket and be retained by locknuts. In theory, you can upgrade Yellow Zinc version one to version two (Black) by using an 8mm bit in a drill press that didn't come from Harbor Freight and get the new hardware. The most recent bracket variant is silver in color has an air pump mount that can be attached or left off depending on your spiritual beliefs and use of an air pump.
Is my description of the differences between version 1 (yellow zinc) and version 2 (black) accurate and complete? Other than the air pump bracket, does the most recent version differ from version 2 and, if so, how?

On the most recent version, the PKT-S, the Audi parts were moved towards the crank gear slightly for greater maximum range. This design now covers most engines, including ones where the heads have been machined.
The early brackets were designed for ease of installation. The 'S'-bracket requires an extra step. Cut into the 'S' is an 8mm hex hole which allows the bracket to be rotated into place around an included 8mm stud (which also plugs the oil-dripping hole).
